Figure 3.

Calcification rates ±s.e. of Lophelia pertusa expressed as µmol CaCO₃ g⁻¹ dry tissue h⁻¹ versus adjusted pCO₂ with linear trend ± 95% CIs at T + 12 months. Black triangles represent aspect ratio ±s.e., of newly formed corallites, with two example images of control and high CO₂ treatments that significantly differed. The shaded area represents water conditions Ω_Aragonite < 1. Asterisks (* and **) denote example corallites represented by the data.
